Stress fractures of the upper limbs are uncommon, and are most often reported as individual cases or small series. In particularly, stress fractures around the wrist are even less common. A stress fracture of the radial styloid process in a judo player was surgically treated, and a favorable treatment outcome was obtained. A 16-year-old adolescent boy experienced pain in the right wrist, with n...

he lack of predictive tools to assess the relative risk of stress fracture injury has posed a great challenge for military readiness and competitive athletic training. This article presents a methodology of assessing such risks using computational models and biomechanical stress analysis in a human femur. Preliminary results have demonstrated the capability of our methodology in studying the ef...

BACKGROUND Sudden emotions may interfere with mechanisms for keeping balance among the elderly. The aim of this study is to analyse if emotional stress and specifically feelings of anger, sadness, worries, anxiety or stress, can trigger falls leading to hip or pelvic fracture among autonomous older people. METHODS The study applied the case-crossover design and was based on data gathered by f...

Stress fracture of the patella is rare. In this report, a case of patellar stress fracture occurring in an amateur athlete is presented, and an operative adjunct to the surgical management of this condition is proposed.A review of the English literature identified 21 previous cases of stress fracture of the patella, the majority in young athletes. None of these reports discussed treatment addre...

[1] A single plane fracture with an axially symmetric stress distribution behaves as a seismic lens that focuses seismic energy to a beam ‘‘waist’’ at a focal plane. Both phase and amplitude effects on a seismic wave propagating across the fracture contribute to the lensing behavior. Radial gradients in the fracture specific stiffness cause wave refraction through a radially varying group time ...

Recent literature shows an association between long-term bisphosphonate therapy and low-energy fractures of the subtrochanteric femur. It is thought that the pharmacology of bisphosphonates and stress characteristics of the subtrochanteric femur predispose patients on long-term therapy to fracture. There are few reports in the literature of bisphosphonate-associated periprosthetic fractures wit...

BACKGROUND Prior studies have identified some risk factors for stress fracture in athletes and military recruits. OBJECTIVE To determine whether historical factors, physical measures, biochemical variables of skeletal metabolism, genetic factors, bone density (BMD) and bone size could predict risk of stress fracture over 4 years in physically fit cadets at the US Military Academy (USMA). ME...

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

A 61-year-old woman presented with acute pain of the right thigh after falling on a public street. She had been diagnosed with metastatic breast cancer and bisphosphonate therapy along with zoledronic acid. Radiographs demonstrated transverse subtrochanteric femoral fracture with thickening of the lateral cortex and spike of the medial cortex at the site of fracture. The contralateral femur sho...

Objective To determine the ideal working area for a simple transverse fracture line treated with a bridge plate. Methods A 2-D finite element analysis of a hypothetical femur was performed for the quantitative evaluation of a large-fragment titanium alloy locking plate based on the precept of relative stability in a case of a simple transverse diaphyseal fracture. Two simulations (one case of...
